> The Assistants API does not support the use of fine-tune models. The documentation had some contrary information, but this has been confirmed as intended. It also could be very expensive when your fine-tune emits repeated errors and you can’t see exactly what’s happening. Only 1106 models support parallel tool calls of retrieval functions, and that is already teetering on the edge where fine-tune could damage it.
